One thing to consider when thinking about risk and infectious disease is the difference between individual and societal risk. Certain activities may have a very low level of risk across society. But are they possible sources of infection? Yes. Could they happen to you? Yes. Unlikely. But yes.
One thing that has been clear for a few weeks is that many of the big outbreaks outside of major cities have been in meat packing plants. That is probably in part because meat packing plants are some of the relatively few kinds of factories or workplaces that have remained open at full capacity. But it’s also in the nature of the plants themselves. (That’s likely why Amazon warehouses, which have been hit as well, haven’t been hit as badly as the meat packing plants.) People are bunched up together. There’s little regard for worker safety and quality of life. They’re natural places for spread.
